Re: Ordering of category option names in the resource tables

 

Reading back through my comment I don't understand it either.  If it
helps, when I said "I don't really understand why the 'name' field
isn't just part of the categoryoption" I meant the
categoryoptioncombo, not the categoryoption.  I think our model jars a
bit here where the categoryoptioncombo table doesn't have a name
field.  I guess because the whole model was geared towards form input,
and there was no need to name the categoryoptioncombo on a form.  But
people found it useful in reporting, so it was added as an
afterthought via the _categoryoptioncomboname table. (still don't see
why a name field wasn't just added instead but I wasn't there).

But this doesn't sound like it should be difficult to fix in its
present form.  The code for DataElementCategoryOptionCombo.getName()
is used to generate the name for the resource tables.  And as far as I
can see this code doesn't take the ordering of categories into
account.  In fact the code for equalsOnName() in the same class is
made quite complicated as a result as it explicitly assumes that the
name is effectively an unordered Set of option names.

So what we'd like to see is that for a given categorycombo with a
given sortorder, the getName() method of all categoryoptioncombos
belonging to that categorycombo will always compose the name according
to the sort order of the categorycombo?

(Bit of a mouthful that.  And can I have it with chips please.)
